Job Stories From Portsmouth, RI
Trustworthy Waterproofing System in Portsmouth, RI

A homeowner in Portsmouth, RI had worked with a couple of different basement waterproofing companies in the past and felt like none of them were honest and helpful. When our inspector met with the owner, he was able to show him the issues that the previous systems had and explained how our TripleSafe sump pump and WaterGuard interior drainage system is the right choice. While the crew was installing the system, they showed the owner all the steps and how it worked multiple times so he could feel reassured that his basement is indeed protected. 

Shallow Sump Pit In Portsmouth, RI

This customer in Portsmouth, RI had a large, but shallow sump pit for her existing sump pump system. After buying this home in 2020, she noticed that the sump pump was not keeping up with the water at all, and she wanted to solve this water issue as soon as possible. When one our inspectors arrived to the basement, he saw how shallow the sump pit was and informed the homeowner that a good sump pit should be deeper than the one she currently has. Once they finalized which sump pump would be the best replacement, a production crew came in to install the TripleSafe sump pump. The sump pit is bigger, meaning it can hold more water while the TripleSafe has plenty of pumping power to discharge during any kind of rainstorm!

Wall Crack Repair System In Portsmouth, RI

A customer in Portsmouth, RI wanted to seal up this wall crack he found in his basement a couple weeks ago before contacting us. He called the right company because we take wall cracks very seriously, as they can seep in moisture or water depending on the size of the crack. This wall crack was wide enough where it was concerning, so we brought out our field technician to perform a quick and effective FlexiSpan wall crack installation. To begin, the technician made a drywell at the bottom of the crack for drainage, then applied flexible polyurethane onto the crack along with a foam strip for extra protection. The design of this system will prevent water from leaking through, and if it does, it will go straight to the drywell to be properly drained.

Wet Dirt Crawlspace in Portsmouth, RI

A customer from Portsmouth, RI contacted our call center so she could waterproof her dirt crawlspace. She was noticing that some of the insulation was beginning to rot since there was so much moisture in the area. That moisture could damage more than just her insulation, so she wanted to fix the problem as soon as she could. Our inspector took a careful look to examine the crawlspace. He pointed out that the insulation needs to be completely replaced, so he had a production team clean out all the debris and placed in our SilverGlo wall insulation. The customer was happy to learn that our radiant heat barrier will keep the crawlspace warm and protected from the outside world!

WaterGuard and TripleSafe Sump Pump Installed In Portsmouth, RI

There was a homeowner in Portsmouth, RI that was looking for a waterproofing system for his half-finished basement. He wanted to complete his basement, but the water seeping in was slowing him down in the process. To get rid of the issue, our production team jackhammered the inside perimeter to place the WaterGuard interior drainage system in. This WaterGuard creates a small gap between the product itself and the wall so that wall seepage can be collected. Then, they replaced the homeowner's current old sump with our TripleSafe sump pump that comes with three pumps! The WaterGuard was then connected to the TripleSafe so that this basement can now collect and discharge water at a much faster rate!
